System.Net.WebSockets Namespace

Provides a managed implementation of the WebSocket interface for developers.

Classes

ClientWebSocket	Provides a client for connecting to WebSocket services.
ClientWebSocketOptions	Options to use with a ClientWebSocket object.
HttpListenerWebSocketContext	Provides access to information received by the HttpListener class when accepting WebSocket connections.
WebSocket	The WebSocket class allows applications to send and receive data after the WebSocket upgrade has completed.
WebSocketContext	Used for accessing the information in the WebSocket handshake.
WebSocketCreationOptions	Options that control how a WebSocket is created.
WebSocketDeflateOptions	Options to enable per-message deflate compression for WebSocket.
WebSocketException	Represents an exception that occurred when performing an operation on a WebSocket connection.
WebSocketReceiveResult	An instance of this class represents the result of performing a single ReceiveAsync operation on a WebSocket.

Structs

ValueWebSocketReceiveResult

Represents the result of performing a single ReceiveAsync(Memory<Byte>, CancellationToken) operation on a WebSocket.

Enums

WebSocketCloseStatus	Represents well known WebSocket close codes as defined in section 11.7 of the WebSocket protocol spec.
WebSocketError	Contains the list of possible WebSocket errors.
WebSocketMessageFlags	Flags for controlling how the WebSocket should send a message.
WebSocketMessageType	Indicates the message type.
WebSocketState	Defines the different states a WebSockets instance can be in.

Remarks

Some of the classes in the System.Net.WebSockets namespace are supported on Windows 7, Windows Vista SP2, and Windows Server 2008. However, the only public implementations of client and server WebSockets are supported on Windows 8 and Windows Server 2012. The classes and class elements in the System.Net.WebSockets namespace that are supported on Windows 7, Windows Vista SP2, and Windows Server 2008 are abstract classes. This allows an application developer to inherit and extend these abstract classes with an actual implementation of client WebSockets.
